Getting ThereThe route starts above Calasima at P.1061m, see the main page.
Route DescriptionFollow the gravel road into viru valley in western direction, Paglia Orba ahead. After half an hour it turns right into NW direction. The detours of the road should me cutted (marked with cairns), passing the "Grotte des Anges" bivy shelter. After re-entering the "road" it climbs to a ford. Right above is the Bergerie Ballone and 30-40 minutes ahead on a marked path (GR20: red and white marks) the Refuge Tighiettu.
In front of the hut turn right (E) and continue up the Ravine Stagni to the next creek coming from the north. The gorge of this creek is to be followed, mainly on the orographical right / western side. Cairns lead across slabs (slippery with rain!) and rock into the Bocca Rossa, where the northern Route is met.
Overall ascending time is 5-6 hours with good conditions. One can split that by staying over night at or next to the Refuge Tighiettu.
